REEF2REEF Saltwater and Reef Aquarium Forum

Not sure if this is the best forum, could go into several. My sump is in my basement, it’s got maybe 200 gallons in it. I was thinking I had things pretty safe with the emergency drain, but it just occurred to me that if somehow the return (or a drain line! Now I’m spiraling ha) became disconnected it would destroy my house. Anyone have any ideas for how a disaster scenario could be averted? Maybe a water detector of some sort on the stand floor to cut power to the main pump downstairs?
